I don't know if the defensive claim a supporting argument, or is it your main point, J. I kinda like it more as a main argument: Ox is absolutely shocking in his defensive approach, he's a completely irresponsibly player there, seems to not have that basic "don't fuck it up close to our goal" instinct, which is infuriating. I'm not sure if it's enough to tilt it, though.
I wonder about that assumption that while Joel needs to be encouraged Ox needs to be kicked up his ass. I'm not at all sure about it, but I tend to think Ox needs the positive Wengery elixirs more - that to find his form in general (not referring to the defensive discipline. There he just needs to be, well, disciplined).
